Method and device for operating a photovoltaic power plant connected in addition to internal combustion generators to a limited power grid

摘要

In a method for operating a photovoltaic power plant which, in addition to a network-forming source, at least one internal combustion generator, which is activated or deactivated by a generator control as required, and at least one load is connected to a limited power grid in order to reduce fuel consumption by feeding power from the photovoltaic power plant To reduce all internal combustion generators, a reserve power (PRes) currently available in the power grid is determined, only activated internal combustion generators being taken into account, and if the determined reserve power (PRes) falls below a minimum reserve power (PRes, min), the feed-in of power reduced by the photovoltaic power plant (PoutPV) to such an extent that the at least one or another internal combustion generator is activated by the generator control.
